A tri-ing reaction: An asymmetric Diels–Alder cycloaddition of δ,δ-disubstituted 2,4-dienones is possible through the trienamine catalysis cinchona-based primary amines (see scheme). array electron-deficient dienophiles, such as N-substituted maleimides and 3-alkenyl oxindoles, were tolerated, multifunctional cyclohexene derivatives obtained in excellent stereoselectivity with high diastereomer ratios. Detailed facts importance to specialist readers are published "Supporting Information"....
A stereoselective inverse-electron-demand aza-Diels–Alder cycloaddition process of cyclic 1-aza-1,3-butadienes and α,β-unsaturated aldehydes has been developed via dienamine catalysis. This reaction exhibits excellent β,γ-regioselectivity for enal substrates with substantial structural diversity broad functionalities, readily producing highly enantioenriched fused piperidine derivatives enabling efficient sequential construction complex polycyclic frameworks.
Electron-deficient 1-aza-1,3-butadienes containing a 1,2-benzoisothiazole-1,1-dioxide or 1,2,3-benzoxathiazine-2,2-dioxide motif act as regio- and chemoselective dienophiles in normal-electron-demand Diels–Alder reactions with HOMO-raised trienamines, rather than typical 4π-participation inverse-electron-demand versions. The enantioenriched cycloadducts could be efficiently converted to spiro fused frameworks high structural stereogenic complexity by sequential aza-benzoin reaction other...
An extended TODIM is proposed in this paper to comprehensively reflect the psychological characteristics of decision makers (DMs) according cumulative prospect theory (CPT). We replace original weight with weighting function CPT and modify perceived value dominance based on CPT, because general phenomena DMs explained are verified by many experiments recognized researchers. Hence, not only integrates advantages considering factors but also retains superiority classical relative dominance....
Abstract This paper aims to help financial institutions identify credit risk and reduce default losses more effectively by improving the accuracy efficiency of evaluation process using two methods. The first mines indicators that comprehensively describe supply chain aspects obtain a precise portrait enterprise. study then innovatively designs random forest‐weighted naive Bayes (RF‐WNB) model offers good interpretability generalization qualities. forms an effective two‐stage enterprise...
Myeloid differentiation primary response protein 88 (MyD88) is crucial to immune cascades mediated by Toll-like receptors (TLRs) and interleukin-1 (IL-1Rs). MyD88 dysregulation has been linked a wide variety of inflammatory diseases, making it promising new target for anti-inflammatory cancer therapy development. In this study, 46 compounds were designed synthesized inspired virtual screen hit. The activity was evaluated biologically, c17 discovered have high binding affinity with MyD88. It...
Multifunktionelle Cyclohexenderivate entstehen bei einer asymmetrischen Diels-Alder-Cycloaddition von δ,δ-disubstituierten 2,4-Dienonen, die über Trienaminkatalyse unter Verwendung primärer Cinchona-Amine abläuft (siehe Schema). Elektronenarme Dienophile wie N-substituierte Maleimide und 3-Alkenyloxindole wurde umgesetzt, Cyclohexene wurden mit ausgezeichneter Stereoselektivität hohem Diastereomerenverhältnis erhalten. Detailed facts of importance to specialist readers are published as...
Small and medium-sized enterprises play a crucial role in sustaining economic development both developed economies developing economies, however, many of them suffer from chronic structural difficulties accessing external financing. In this paper, we develop theoretical framework to illustrate how information structures work the strategic interactions between banks firms supply chain, why transaction chain may serve reduce asymmetry improve SMEs’ access We find that under incomplete...
Here we report that Morita-Baylis-Hillman carbonates from diverse aldehydes and methyl vinyl ketones can be directly utilised as palladium-trimethylenemethane 1,4-carbodipole-type precursors, both reactivity enantioselectivity are finely regulated by adding a chiral ammonium halide the ion-pair catalyst. The newly assembled intermediates, proposed to contain an electronically neutral π-allylpalladium complex reactive compact ion pair, efficiently undergo asymmetric [4 + 2] annulations with...
Abstract An asymmetric Diels–Alder cycloaddition reaction of quinone imine ketals and 2,4‐dienals has been investigated via trienamine catalysis a secondary chiral amine. A series tricyclic benzo[ de ]quinolone derivatives were efficiently constructed in moderate to good yields with high excellent enantioselectivity after cascade aromatization/intramolecular hemiaminal formation sequence (up 98% ee , >19:1 dr ). The methodology the useful product scaffolds could be further utilized both...
Abstract Creativity, the ability to generate original and valuable products, has long been linked semantic retrieval processes. The associative theory of creativity posits flexible as an important basis for creative idea generation. However, there is insufficient research on how memory acts activities. This study aimed capture different dynamic aspects processes examine behavioral neural associations between flexibility creativity. We developed 5 metrics quantify based previous studies,...
